[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0055] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0056] At present, the traditional archival retrieval method of ruins mainly requires users to enter keywords, titles, years covered, authors and other search conditions related to the archival materials in the human-computer interaction interface of the terminal device. The terminal device pushes relevant archival materials to the user based on the search conditions entered by the user to complete the archival retrieval of ruins. However, this solution does not unify the metadata contained in the archival materials of the ruins, which results in low efficiency and low retrieval accuracy of archival retrieval of ruins, and it is difficult to meet the needs of research, study and education of city wall ruins.

[0057] To this end, the embodiment of the present application provides a classification retrieval method for site archival materials, which obtains site archival materials and digitizes the site archival materials; performs metadata annotation on the digitized site archival materials based on a pre-built metadata model to obtain metadata corresponding to the site archival materials; classifies the site archival materials according to the metadata corresponding to the site archival materials, and classifies and stores the site archival materials according to the classification results of the site archival materials; and recommends target retrieval results to users based on the search content input by the user and the metadata corresponding to the site archival materials. In this way, the effect of improving the retrieval efficiency and retrieval accuracy can be achieved while promoting the sharing and dissemination of site archival resources.

[0058] The following is a detailed explanation of the classification and retrieval method of archival materials of ruins provided in the embodiment of the present application in conjunction with the accompanying drawings.
